Re: Backup Large Tables

Are you dumping the whole database or just a single table? If it's
the former, try the latter and see if you still get errors.

If pg_dump is not working, maybe some system table is hosed. What
errors are you getting?

If you can get in via psql, log in as a superuser and execute:

COPY mytable TO 'mytable.txt';

That will dump the table data to a text file which can be re-imported
into a new database using the COPY FROM command. Basically you're
just doing part of what pg_dump does for you by hand.
